Equal stride super-buffer Rx mode is supported by DPDK firmware
variant. One Rx descriptor provides many Rx buffers to firmware.
Rx buffers follow each other with specified stride.
Also it supports head of line blocking with timeout to address
drops when no Rx descriptors are available. So it gives extra time
to the driver to provide Rx descriptors before drop.

Packed stream firmware variant on EF10 adapters has a
number of properties which must be taken into account:
- Only one exclusive RSS context is available per port.
- Only IP addresses can contribute to the hash value.
Huntington and Medford have one more limitation which
is important for the drivers capable of packed stream:
- Hash algorithm is non-standard (i.e. non-Toeplitz).
This implies XORing together source + destination
IP addresses (or last four bytes in the case of IPv6)
and using the result as the input to a Toeplitz hash.
This patch provides a number of improvements in order
to treat the mentioned limitations in the common code.
If the firmware variant is packed stream, the list of
supported hash tuples will include less variants, and
the maximum number of RSS contexts will be set to one.

This patch provides basic infrastructure for the new interface.

will be possible to configure hashing by means of new definitions.

Add filter match flag to distinguish filters applied only to
encapsulated packets.
Match flags set should allow to determine whether a filter
is supported or not. The problem is that if specification
has supported set outer match flags and specified
encapsulation without any inner flags, check says that it
is supported, and filter insertion is performed. However,
there is no filtering of the encapsulated traffic. A new
flag is added to solve this problem and separate the
filters for the encapsulated packets.

- Init the clip table during attach and teardown during detach.
- While here, add a dev.<nexus>.<unit>.misc.clip sysctl to dump the

This does mean that we update the clip table even if TOE is not enabled,

is calculated to guarantee that struct uma_slab is placed at pointer size
alignment. Calculation of real struct uma_slab size is done in keg_ctor()
and yet again in keg_large_init(), to check if we need an extra page. This
calculation can actually be performed at compile time.
- Add SIZEOF_UMA_SLAB macro to calculate size of struct uma_slab placed at
an end of a page with alignment requirement.
- Use SIZEOF_UMA_SLAB in keg_ctor() and in keg_large_init(). This is a not
a functional change.
- Use SIZEOF_UMA_SLAB in UMA_SLAB_SPACE definition and in keg_small_init().
This is a potential bugfix, but in reality I don't think there are any
systems affected, since compiler aligns struct uma_slab anyway.
The first packet after the ring is initialized was never
completed as isc_txd_credits_update() would not include it in the
count of completed packets. This caused netmap to never complete
a batch. See PR 233022 for more details.

A related future change, which changes KERNBASE for Book-E for some reason
causes a "KERNBASE redefined" error with assym.inc, even though it only changed
the value of KERNBASE and nothing else. Since machine/vmparam.h is already
included in booke/locore.S, and the requisite guards are already in place for
properly handling KERNBASE in vmparam.h, just remove it from genassym, and
include vmparam.h in the AIM locore files.
